Time Series Analysis in SQL Server

1

Choosing the appropriate data type

In this chapter, you will learn what are the most used data types in SQL Server. You will understand the differences between implicit and explicit conversion and how each type of conversion manifests. You will also get familiar with the functions used for explicitly converting data: CAST() and CONVERT().

Welcome to this course!

Working with different types of data

Storing dates in a database

Types of character strings

Implicit conversion

Implicit conversion between data types

Data type precedence

Explicit conversion

CASTing data

CONVERTing data

Working with the correct data types

Functions for positions

Calculating the length of a string

Looking for a string within a string

Looking for a pattern within a string

Functions for string transformation

Changing to lowercase and uppercase

Using the beginning or end of a string

Recognizing Numeric Data Properties

In this chapter, you will work with functions applied to numeric data. You will use aggregate functions for calculating the minimum, maximum or the sum of values from a set. You will learn how to raise a number to a power or to calculate its square root.

Aggregate arithmetic functions

Learning how to count and add

MINimizing and MAXimizing some results

Analytic functions

Accessing values from the next row

Accessing values from the previous row

Getting the first and last value

Mathematical functions
